Running back Spencer Ware, the Seahawks’ sixth-round pick in last month’s NFL Draft, signed his rookie contract today.

Ware is being used at fullback and tailback by the Seahawks, and his wares have been on display at last weekend’s rookie minicamp as well as the team’s offseason-program workouts this week.

“I want him to learn how to play fullback for us and compete at that spot,” coach Pete Carroll after watching Ware over the weekend. “We’ve seen him run the ball a lot and we know he can. He’s a really aggressive, tough runner and we love that about him. So we’re trying to transfer that nature to the fullback spot.”

In three seasons at LSU, the 5-foot-10, 229-pound Ware rushed for 1,249 yards, including 707 in 2011; and caught 39 passes, with 18 of his receptions coming last season.

Still unsigned are running back Christine Michael, who was drafted in the second round; cornerback Tharold Simon (fifth) and tackle Michael Bowie, the last of the team’s four selections in the seventh round.
